 |
|
I have an array with several values. I want to remove the duplicate values.
| Code: |
Example
Name1 Name2 Flag
Pink Floyd D
Jack Daniel
James Bond I
Mike Jackson
Dave Seibert I
Pink Floyd I
James Bond D
|
The duplicates will always have a flag. I want to discard the duplicate names with the flag I
Expected output
| Code: |
Name1 Name2 Flag
Pink Floyd D
Jack Daniel
Mike Jackson
Dave Seibert I
James Bond D |

shuko,
Are you reading a file and loading these values into an array or how is the array populated?
If you are reading from a file or a DB2 table you can eliminate the dups right when you are loading the array it self

I am reading a file and populating the array and then I do some processing
with the values in the array. The duplicates are causing a problem for me. |

shuko,
Try this code.
| Code: |
01 W-NAMES-TABLE.
05 W-NAMES-TBL OCCURS 0 TO 30000 TIMES
INDEXED BY W-NAMES-NDX.
10 W-FULL-NAME.
15 W-FIRST-NAME PIC X(10).
15 W-LAST-NAME PIC X(10).
10 W-NAME-IND PIC X(01).
01 W-NAME-KEY.
05 W-FNAME-KEY PIC X(10) VALUE SPACES.
05 W-LNAME-KEY PIC X(10) VALUE SPACES.
OPEN FILE
READ FILE
PERFORM 1000-LOAD-INTERNAL-TABLE UNTIL END-OF-FILE
1000-LOAD-INTERNAL-TABLE
MOVE FILE-FIRST-NAME TO W-FNAME-KEY
MOVE FILE-LAST-NAME TO W-LNAME-KEY
SET W-NAMES-NDX TO 1
SEARCH W-NAMES-TBL
AT END
MOVE W-NAMES-REC TO W-FULL-NAME(W-NAMES-NDX)
MOVE FILE-IND TO W-NAME-IND(W-NAMES-NDX)
WHEN W-FULL-NAME(W-NAMES-NDX) = W-NAME-KEY
CONTINUE
END-SEARCH
READ FILE
.

Kolusu,
| Code: |
...
WHEN W-FULL-NAME(W-NAMES-NDX) = W-NAME-KEY
EVALUATE W-NAME-IND(W-NAMES-NDX)
WHEN 'I'
MOVE FILE-IND TO W-NAME-IND(W-NAMES-NDX)
WHEN OTHER
CONTINUE
END-EVALUATE
END-SEARCH
|
when there is a dup, and the table item is an I, you need to change it. Does not matter if the FILE-IND is I or D.
